Title: Sealed rotating electric machine
Inventor: TSUKIJI MAKOTO
IPC: H02K5/12
Filed: 1994-06-06
Abstract: PURPOSE:To provide a reliable rotating electric machine which reduces capacitive currents or resistive currents by a heater inside a sealed casing. CONSTITUTION:A sealed rotating electric machine is equipped with a heater 7 at the bottom of the sealed casing 1 where medium 6 is in liquid form. And, in the case of starting the sealed machine after a long period of suspension, the medium such as a refrigerant, cooling machine oil, or the like is heated by supplying the heater 7 with a current for a certain time before the start of the sealed machine by a timer or the like. As a result, convection or partial boiling occurs in the medium, which mixes and agitates the medium, and also forms bubbles in the medium, and it gets in an air-liquid mixed condition, so that apparent volume resistance rate between the charger of winding and a grounding potential section becomes large and the dielectric constant becomes small. Accordingly, capacitive currents and resistive currents flowing through the section where grounding potential is to be retained can be reduced, so the reliability on equipment can be raised.

Abstract: PURPOSE:To change the angle of a lens barrel with a high precision by engaging an input gear, which is rotated by a driving means, with a spur gear or an internal gear fixed to the lens barrel with plural idle gears different in number of teeth between them. CONSTITUTION:An internal gear 6 is fixed to a lens barrel 2, and an input gear 9 is engaged with this gear 6 with two idle gears 7 and 8 different in number of teeth between them. This input gear 9 is turned by a motor M (driving means) to change the angle of the lens barrel 2 in the declination direction of an arrow A. Since two idler gears 7 and 8 are different in number of teeth from each other, engaged tooth forms are always different between engagement among the input gear 9, the idler gear 7, and the internal gear 6 and that among the input gear 9, the idler gear 8, and the internal gear 6, and rotation speeds are different from each other, and therefore, friction states are different from each other and it is difficult to generate play. Consequently, the angle of the lens barrel 2 in the declination direction of the arrow A is changed with a high precision without backlash for a long time.

Title: Variable magnification copying method
Inventor: HASHIMOTO OSAMU
IPC: G03G15/04
Filed: 1989-05-16
Abstract: PURPOSE:To prevent a photosensitive sheet from being used uselessly by delaying the drawing-out start timing of the photosensitive sheet at the time of enlargement copying against the time of unmagnification copying. CONSTITUTION:At the time of unmagnification, the speed of an optical system device coincides with a medium sheet carrying speed, therefore, a motor M1 for driving an optical system and a motor M2 for driving a buffer roller are started simultaneously. Also, based on the unmagnification as a reference, the time T2 for delaying a driving start of the buffer roller at the time of enlargement magnification R becomes T2=(M.R-B)/S. In this regard, M denotes the approach distance of an optical system device. That is, at the time of enlargement copying, the T2 time is calculated from the 2 expression and after the T2 time elapses after the movement of the optical system is started, the buffer roller is driven. In such a manner, the drawing-out quantity of a medium sheet at the time of enlargement copying is reduced, therefore, the medium sheet can be saved.
